Using WhatsAppApi.NET how to send a message

Liam Campbell

I am using the WhatsAppApi.NET to send whats app messages however i dont know how to get a access code for my phone number as i see that https://github.com/mgp25/WART code generator no longer works

So is there a Free way to use this package and get a access code for my phone.

This is my code for the api so far for the console app C#

static void Main(string[] args) {
string password = "";
string Nickname = "Joe";
string Fromnumber = "121312432";
string ToNumber = "12312434";
string msg = "";
WhatsApp wap = new WhatsApp(Fromnumber, password, Nickname, false, false);
wap.OnConnectSuccess += () =>{
Console.WriteLine("Connection Successfully");
wap.OnLoginSuccess += (PhoneNumber, data) =>{
wap.SendMessage(ToNumber, msg);
Console.WriteLine("Message Sent!");
};
wap.OnLoginFailed += (data) =>{
Console.WriteLine("Login Fail due to {0}", data);
};
wap.Login();
};
wap.OnConnectFailed += (ex) =>{
Console.WriteLine("Connection Failed...");
};
Console.ReadLine();
}

Its too hard for an individual to get the Whatsapp Business API from them (directly), you have to use 3rd party service provider for communication.

You can request by sharing your company details, if they found useful then you can get the API directly

the other option is whatsapp business
https://developers.facebook.com/docs/whatsapp/getting-started
check , it also seems a paid one, and obviously for commercial use , things are paid.

I have tried Twilio out and that works in some ways but it does not offer any flexability and is only a free trial so has to be paid for eventually, does anyone know a long term free solution?

Hey

WART authentication is almost dead from a very long time ago (years), you can grab the service from 3rd party service provider (like twillio or any) and do your stuffs.

As @Sachin had mentioned the link (2nd one)

Good Luck!!
